The affected file may be 0 KB or smaller than expected. This suggests truncating the ZL9 file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our ZL9 file. Sometimes virus-infected ZL9 files cannot be recovered, so make a backup in advance.
Older version of ZL9 file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular ZL9 file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted ZL9 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the ZL9 file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file ZL9 to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
